Zusammenfassung:The invention discloses a preparation method of powder for an end cover of an air condition compressor. According to the preparation method, raw materials comprise iron scale, coke powder, limestone flour, flue ash, aluminum dihydrogen phosphate and trimethylolpropane, and a mass ratio of the raw materials is 100: (26-40): (2-4): 1: (0.6-0.8): (0.1-0.13). With the adoption of the method, the air tightness is good, and the pressure can be maintained for 48 h under 16 atmospheric pressures; iron powder imported from Quebec, Canada is replaced with the powder prepared with the method; the service life of the air condition compressor can be prolonged, and the refrigeration effect of the air condition compressor can be improved.
